On the Quantum Theory of Line–spectra
... In fact we have assumed that the direct transition between two such states cannot be described by ordinary mechanics, while on the other hand we possess no means of defining an energy difference between two states if there exists no possibility for a continuous mechanical connection between them. It ...

... as string duality: a strongly coupled limit of any given string theory is equivalent to a weakly coupled limit of another one.7 In other words, as we take the coupling large (i.e. in the gs → ∞ limit), the theory actually simplifies, and can be described perturbatively in some dual variables. Though ...

Mathematics via Symmetry - Philsci
... symmetry that relates matter to forces in nature. Supersymmetry requires us to postulate the existence of a partner matter particle for every known particle that carries a force, and a force particle for every matter particle. The idea here is that the laws of physics are invariant if we swap all th ...

Spin Hamiltonians and Exchange interactions
... may consider a spin as having a definite direction, just as in the limit of small ~ we may consider an object as having both position and momentum well-defined. Semiclassical spin dynamics This result below can be thought of as the analog for spins of Newton’s equations; the condition for static equ ...

Finite-Volume Electromagnetic Corrections to the Masses of Mesons
... when the electromagnetic gauge field is subject to periodic boundary conditions (PBCs) [15–17]. However, a uniform background charge density can be introduced to circumvent this problem and restore these laws. This is equivalent to removing the zero modes of the photon in a finite-volume (FV) calcul ...

A pseudo-mathematical pseudo-review on 4d N = 2
... The author’s opinion is that we need to push this view point one step further, by regarding QFTs themselves as objects in something like a category. The important point is that a QFT (although not usually rigorously constructed mathematically) is a mathematical object, much like a group, a space or ...
